From PC to server, from Internet to the Wifi, the future portable terminal installations and other kinds of applications have already expressed the huge potential.In the design field, people need some effective methods to combine the traditional design patterns and the digital technology.A design revolution based on the mobile Internet is extremely urgent.Under this background, this paper summarizes the whole process of design of handheld terminals and Cloud Application of BIM; proposes the solutions and analysis; hopefully opens a new way for readers to design in the digital aera.

The application of foundation pit 5D monitoring and 3D geological model technology based on BIM increased the work efficiency and reduced the man-made omission effectively of safety monitoring during the process of foundation pit construction depending on the visual method. At the same time, in this project, the application of new demonstrating technologies and mobile media equipment such as 3D GIS, 3D laser scanning, 3D printing, AR, VR, Google Glass and so on made the safety monitoring during the process of foundation pit construction operated by project managers, supervisors, monitors more effective. The extended application of BIM technology on the foundation pit safety monitoring of the Poly Plaza explored a new method about foundation pit safety monitoring, and it also provided a useful reference on the application of BIM technology during the whole process of construction of foundation pit engineering.

This paper briefly introduced the application experience of ArchiCAD software in the design of Anshan sports center natatorium.Through using ArchiCAD to perform BIM design, the problem of spatial structure complex was solved.More important is, from the conceptual design to the final detailed working drawing, project forms and statistical computer, all the works were performed in ArchiCAD.Full localization and optimized workflow not only greatly enhanced the efficiency, but also enhanced the quality of design and drawings.In the cooperation, through importing and exporting files of IFC, DWG, 3DS, implored exchanging the data of building information and structural, HVAC.Rendering, animation, virtual reality and so on, are the byproducts of design.

Nowadays, with the limitations of tranmission softwares unable to transmit models from Revit into computing softwares accurately and efficiently, the efficiency of structural design is reduced significantly when adopting BIM design. Based on the frane and bent structure of thermal power plant building.this paper analyses the design flow and functional features of Revit, put forward a new solution of linking up Revit 2016 and STAAD.Pro, and proposes suggestions for perfection in Revit.

Data-based collaborative management of investigation & design started earlier in Japan. This paper introduced its current situation and future challenge from CAD exchange standard, BIM-based collaborative design and lifecycle data sharing. In comparison with Chinese situation, we give out some suggestions about how to improve our collaborative management from data standardization and information system.

3D modeling is one of the most primary features of BIM and Architecture CAD software. In this paper, we made a deep investigation into geometry kernels and modelers which are being used by current most popular and influenced BIM and Architecture CAD software. By evaluating, testing, comparing and applying three kernels, we got the suggestion and rules of using them, which could be a guide of designing and developing BIM software in the future.

With the "Cloud" technology and the development of the Internet, all kinds of application platforms and end use increase rapidly. It is more difficult for professional users of the Internet to obtain and deal with information, and the cost of design management is increased. The unequal mass information and information access lead to high costs, which restricts the efficiency of the professional use of information. The mature cloud platform for professional users of information has professional and efficient features. It can improve the overall level of the information utilization of the design staff through certain technical means and process modes, make the design more convenient, and reduce the cost of the design management.

As a large-scale infrastructure, railway projects not only possesses characteristics of long construction period and large resource consumption, but also involves more complex construction techniques than construction projects, as well as facing the tests of natural environment. It is the future development trend of railway engineering to apply the BIM technology in railway construction. This paper introduces the application of BIM technology in Qingdao West Railway Station of Qinglian Railway, including: organization structure, hardware and software construction, deepening design, BIM + GIS application, and project management process based on BIM collaborative office cloud platform. The application effect of BIM is demonstrated in this paper. The results show that the application of BIM has brought significant effect to improve the efficiency and efficiency of railway industry.

BIM agrees with prefabricated building naturally. Thus this paper puts forward a view point that the value of BIM embodies in the fact that its 3D entity model provides the basic digital object for management collaboration. Around this viewpoint, this paper discusses the technical characteristics and application direction of BIM, including the version iteration, component recognition, model manipulation, and etc. Then, based on the discussion above, the key technical problems and solutions are explored, including the lightweight strategy based on data form, hybrid application of database, model display and control and associated management information on Web, QR code and RFID, and etc. At last, the prototype system is developed, and its effectiveness is verified through the actual engineering case.

Jingtianlutu is the first BIM software for highway engineering in domestic transportation industry. Addressing the issue of the software's inability to quickly analyze the bearing capacity of multi-layered geological bodies, an interface program between Jingtianlutu and the common bearing capacity analysis software FLAC^3D was developed using the C# language on the Visual Studio 2019 platform, based on the 3D WinForms control Eyeshot. The interface program has a graphical display interface, which can read the terrain data of multi-layered geological bodies from the Jingtianlutu, and layer the geological bodies according to the geological survey data, and obtain the geometry data and material properties of each stratum. The finite element mesh model is automatically created in ANSYS using the APDL command flow. Utilizing the FLAC^3D command flow, the pre-processing tasks such as reading and converting mesh models, defining material properties and boundary conditions are automatically completed before the solution process begins. Commonly used analysis results are then automatically exported and sent back to Jingtianlutu. This study provides detailed information on the research and implementation ideas, development tools, development processes, and key algorithms of the interface program. An example is used to verify the interface program, demonstrating that the analysis results of the bearing capacity of multi-layered geological bodies using the interface program are consistent with the results obtained through direct use of ANSYS modeling and FLAC^3D calculation. However, the former takes approximately 2 minutes, while the latter takes around 0.6 hours, which significantly enhances the efficiency of designers.
